DETAILED DESCRIPTION

Before any embodiments of the invention are explained in detail, it isto be understood that the invention is not limited in its application tothe details of construction and the arrangement of components set forthin the following description or illustrated in the following drawings.The invention is capable of other embodiments and of being practiced orof being carried out in various ways.

FIGS. 1 and 2 illustrate a security apparatus 100 embodying theinvention. The security apparatus 100 is configured to engage a portableelectronic device 104 (FIG. 16) (e.g., a tablet computer, a laptopcomputer, a smartphone, an mp3 player, an eReader, etc.) to secure theportable electronic device 104 at a location. The illustrated securityapparatus 100 includes a force-transmission member 108 (FIGS. 3-7), alock head 112, and an actuator assembly 116. The lock head 112 and theactuator assembly 116 are coupled to opposite ends of theforce-transmission member 108 so that the actuator assembly 116 islocated remote from the lock head 112. This arrangement positions theactuator assembly 116 apart from the portable electronic device 104 sothe actuator assembly 116 does not interfere with and/or block otherports, buttons, or sections of the portable electronic device 104.

As shown in FIGS. 3-7, the illustrated force-transmission member 108 isa cable having a length, a first end 120, and a second end 124. The lockhead 112 (FIGS. 3-5) is coupled to the first end 120 of the cable 108.The actuator assembly 116 (FIGS. 6-7) is coupled to the second end 124of the cable 108. As used herein, “end” refers to the portion of thecable 108 that is received in and coupled to the lock head 112 or theactuator assembly 116, and not necessarily to the absolute terminus ofthe cable 108. Connecting the lock head 112 and the actuator assembly116 to opposite ends of the cable 108 spaces the actuator assembly 116 adistance D (FIG. 2) from the lock head 112. The distance D is measuredalong the length of the cable 108 and is not necessarily the shortestdistance between the lock head 112 and the actuator assembly 116. Inaddition, the distance D is fixed in that even though the cable 108 maybend, the cable 108 does not compress. As such, the distance D betweenthe lock head 112 and the actuator assembly 116, when measured along thelength of the cable 108, remains constant.

An outer sheath 128 surrounds the cable 108 to protect and strengthenthe cable 108. The outer sheath 128 maintains the lock head 112 at thedistance D, along the length of the cable 108, from the actuatorassembly 116. The cable 108 is movable relative to the outer sheath 128to move and actuate the lock head 112. In the illustrated embodiment,the cable 108 slides within the outer sheath 128. The cable 108 and theouter sheath 128 are also flexible to allow the lock head 112 and theactuator assembly 116 to move relative to each other, yet still retainthe distance D between the lock head 112 and the actuator assembly 116.In other embodiments, the cable 108 and/or the outer sheath 128 may berigid structures that do not bend or flex. In some embodiments, thedistance D between the lock head 112 and the actuator assembly 116 is atleast 8 cm. In other embodiments, the distance D may be longer orshorter (e.g., 5 cm, 10 cm, 1 m, etc.), depending on the desiredapplication or use of the security apparatus 100.

As shown in FIGS. 3-5, the lock head 112 is coupled to the first end 120of the cable 108. At least a portion of the lock head 112 is configuredto be received in an opening or slot 132 formed in the portableelectronic device 104. When positioned within the slot 132, the lockhead 112 selectively engages the portable electronic device 104 tosecure the security apparatus 100 to the device 104. In particular, thelock head 112 is movable between a first, unlocked position (FIG. 4) anda second, locked position (FIG. 5).

The illustrated lock head 112 includes a body 136, an expandable portion140, a plunger 144, and a biasing member 148. A portion of the body 136is removed in FIGS. 3-5 to help illustrate the internal components ofthe lock head 112. The body 136 receives a portion of the outer sheath128 that is adjacent the first end 120 of the cable 108 to fix the lockhead 112 to the sheath 128. In some embodiments, the outer sheath 128may be clamped and/or glued within the body 136. The body 136 alsohouses and supports the other components of the lock head 112.

The expandable portion 140 is coupled to and extends outwardly from thebody 136. In the illustrated embodiment, the expandable portion 140extends axially from the body 136 and is generally aligned with alongitudinal axis of the cable 108 when the cable 108 is straightened.The illustrated expandable portion 140 includes two spaced apart latches152. The latches 152, or tabs or fingers, are movable relative to thebody 136 between the unlocked position (FIG. 4) and the locked position(FIG. 5). An elastomeric element 156 (e.g., an O-ring or rubber band)surrounds the latches 152 to help bias the latches 152 toward theunlocked position. The elastomeric element 156 also seals an end of thebody 136. When in the unlocked position, the latches 152 are positionedradially inward so that the latches 152 are spaced apart from anddisengage the portable electronic device 104. In this position, the lockhead 112 can be inserted into and removed from the slot 132 in thedevice 104. When in the locked position, the latches 152 are moved(e.g., pivoted) away from each other and radially outward relative tothe body 136. In this position, the latches 152 engage the portableelectronic device 104 to secure the lock head 112 to the device 104. Inother embodiments, the expandable portion 140 may include other types orconfiguration of latches suitable for engaging the portable electronicdevice 104. For example, in some embodiments, the expandable portion 140may include latches that are at least partially composed of a resilientmaterial so that the latches are naturally biased toward the unlockedposition (e.g., toward each other). Additionally or alternatively, theexpandable portion 140 may include three or more latches or only asingle latch that engages the device 104.

The illustrated plunger 144, or wedge, is positioned partially withinthe body 136 and between the latches 152 of the expandable portion 140.In the illustrated embodiment, the plunger 144 includes a tapered ornarrow portion 160 and a flared or wide portion 164. The tapered portion160 of the plunger 144 is coupled to the first end 120 of the cable 108.The flared portion 164 of the plunger 144 is the distal, free end of theplunger 144. In operation, the cable 108 pulls the plunger 144 in thedirection of arrow A when actuated by the actuator assembly 116 to movethe lock head 112 from the unlocked position to the locked position.When the lock head 112 is in the unlocked position (FIG. 4), the taperedportion 160 of the plunger 144 is aligned with the latches 152 so thatthe latches 152 are biased radially inward by the elastomeric element156. When the lock head 112 is in the locked position (FIG. 5), theflared portion 164 is aligned with and engages the latches 152 to pushthe latches 152 radially outward.

The biasing member 148 is positioned within the body 136 and coupled tothe plunger 144. The biasing member 148 biases the plunger 144 towardthe unlocked position (i.e., in the direction opposite the arrow A) sothat the tapered portion 160 of the plunger 144 is aligned with thelatches 152. In the illustrated embodiment, the biasing member 148 is acoil spring that is wrapped around the first end 120 of the cable 108.In other embodiments, other suitable biasing members may also oralternatively be employed.

As shown in FIGS. 6 and 7, the actuator assembly 116 is coupled to thesecond end 124 of the cable 108. The actuator assembly 116 is operableto actuate (e.g., pull) the cable 108 to move the lock head 112 betweenthe unlocked position and the locked position. The illustrated actuatorassembly 116 includes a body 168, a movable member 172, a manualactuator 176, and a lock mechanism 180. A portion of the body 168, orframe, is removed in FIGS. 6 and 7 to facilitate illustration of theinternal components of the actuator assembly 116. The body 168 receivesa portion of the outer sheath 128 adjacent the second end 124 of thecable 108 to fix the actuator assembly 116 to the sheath 128. In someembodiments, the outer sheath 128 may be clamped and/or glued within thebody 168. The body 168 houses and supports the other components of theactuator assembly 116.

The movable member 172 is positioned within the body 168 and coupled tothe second end 124 of the cable 108 by a ferrule 182. The ferrule 182 issecured to the cable 108 and abuts the movable member 172 such thatmovement of the member 172 also moves the ferrule 182 and the cable 108.The illustrated movable member 172 is a ramp including a first inclinedor ramped surface 184 that cooperates with the manual actuator 176. Asshown in FIGS. 8A and 8B, the movable member 172 also includes aprojection 188, or tooth, having an inclined or ramped surface 192 and astop surface 196 that cooperate with the lock mechanism 180. In theillustrated embodiment, the first ramped surface 184 is formed in anupper surface of the movable member 172, and the second ramped surface192 and the stop surface 196 are formed in a side of the movable member172. The movable member 172 is movable within the body 168 toselectively pull and release the cable 108. When the movable member 172pulls the cable 108, the cable 108 in turn pulls the plunger 144 (FIGS.4 and 5) to move the lock head 112 to the locked position. When themovable member 172 releases the cable 108, slack is created in the cable108 so that a biasing member 200 biases the movable member 172 towardthe lock head 112. In the illustrated embodiment, the biasing member 200is a coil spring that surrounds a portion of the cable 108. In otherembodiments, other suitable types of biasing members may also oralternatively be employed.

Referring back to FIGS. 6 and 7, the manual actuator 176 is supported byand extends out of the body 168. In the illustrated embodiment, theactuator 176 is a push button that is depressible by a user to move theactuator 176 relative to the body 168. In other embodiments, othersuitable actuators (e.g., levers, dials, etc.) may also or alternativelybe employed. The actuator 176 includes an inclined or ramped surface 204that engages the first ramped surface 184 of the movable member 172. Theactuator 176 is movable between a first, extended position (FIGS. 6 and8A-8B) and a second, depressed position (FIGS. 7 and 9A-10B). When inthe first position, the actuator 176 is fully extended from the body168. In this position, the movable member 172 can move toward the lockhead 112 under the force from the biasing member 200, thereby releasingthe cable 108 so that the lock head 112 is movable to the unlockedposition. When in the second position, the actuator 176 is depressedrelative to the body 168. In this position, the movable member 172 ispushed away from the lock head 112 against the force from the biasingmember 200, thereby pulling the cable 108 to move the lock head 112 tothe locked position.

As shown in FIGS. 8A, 9A, and 10A, the illustrated lock mechanism 180includes a lock cylinder 208, a lock member 212, and a biasing member216. The lock cylinder 208 is positioned within the body 168 and isconfigured to receive a key. In the illustrated embodiment, the key isoperable to selectively unlock the lock mechanism 180 and, thereby,selectively allow movement of the actuator 176 relative to the body 168and the movable member 172. In other embodiments, the key may beoperable to both selectively lock and unlock the lock mechanism 180. Thelock member 212, or toggle, is coupled to an end of the lock cylinder208 for movement relative to the lock cylinder 208. The illustrated lockmember 212 includes a projection 220 extending toward and engaging themovable member 172. The projection 220 includes an inclined or rampedsurface 224 and a back surface 228. The ramped surface 224 defines arecess 232 that is shaped and sized to receive the tooth 188 of themovable member 172. The recess 232 divides the projection 220 into twolobes 220A, 220B (FIGS. 8B, 9B, and 10B). The back surface 228 is formedon the second lobe 220B. The lock member 212 is movable (e.g.,rotatable) between a first position (FIGS. 8A-8B and 10A-10B), in whichthe projection 220 extends toward the movable member 172, and a secondposition (FIGS. 9A-9B), in which the projection 220 is pivoted away fromthe movable member 172 (e.g., downward in the figures). The biasingmember 216 is coupled to the lock member 212 to bias the lock member 212toward the first position. In the illustrated embodiment, the biasingmember 216 is a torsion spring. In other embodiments, other suitablebiasing members may also or alternatively be employed.

FIGS. 8A-10B illustrate operation of the actuator assembly 116.Initially, when the security apparatus 100 is in the unlocked position(FIGS. 8A-8B), the manual actuator 176 is in the extended position, themovable member 172 is pushed by the biasing member 200 toward the lockhead 112, and the lock member 212 extends toward the movable member 172so that the recess 232 receives the tooth 188. From this position, themanual actuator 176 can be depressed by a user to move the securityapparatus 100 to the locked position. In particular, depressing themanual actuator 176 in the direction of arrow B causes the rampedsurface 204 of the actuator 176 to push against the first ramped surface184 of the movable member 172. The movable member 172 is then pushedaway from the lock head 112. As the movable member 172 moves away fromthe lock head 112, the second ramped surface 192 on the tooth 188 pushesagainst the ramped surface 224 of the lock member 212, causing the lockmember 212 to rotate in the direction of arrow C, as shown in FIGS.9A-9B. The lock member 212 continues to rotate until the projection 220(more particularly, the second lobe 220B) clears the apex of the tooth188. Once the projection 220 clears the tooth 188, the lock member 212is automatically rotated in the direction opposite arrow C under theforce of the biasing member 216 to extend back toward the movable member172, as shown in FIGS. 10A-B. In this position, the back surface 228 ofthe projection 220 engages the stop surface 196 of the tooth 188 toinhibit movement of the movable member 172 toward the lock head 112. Thelock mechanism 180, thereby, holds the manual actuator 176, the movablemember 172, and the lock head 112 in the locked position.

To release the lock head 112 from the locked position, a suitable key isinserted into the lock cylinder 208 and turned to move (e.g., rotate)the projection 220 of the lock member 212 temporarily out of engagementwith the movable member 172. In particular, actuating the lock mechanism180 with the key rotates the lock member 212 in the direction of arrow C(FIGS. 8A and 9A). As the lock member 212 rotates, the back surface 228on the projection 220 slides along the stop surface 196 of the tooth188. Once the projection 220 clears the tooth 188, the movable member172 is movable back toward the lock head 112 under the force of thebiasing member 200. Moving the movable member 172 toward the lock head112 releases the cable 108 so that the lock head 112 also moves to theunlocked position. In addition, moving the movable member 172 toward thelock head 112 raises the manual actuator 176 back to the extendedposition (i.e., in the direction opposite arrow B). The manual actuator176, the movable member 172, and the lock head 112 are then held in theunlocked position until the actuator 176 is depressed again.

In other embodiments, the cable 108 may be a different type offorce-transmission member. For example, the force-transmission member108 extending between the lock head 112 and the actuator assembly 116may be a rigid structure, such as a rod. In this arrangement, theactuator assembly 116 may push the rigid force-transmission member (and,thereby, the plunger 144) to move the security apparatus 100 to thereleased position. In addition, the actuator assembly 116 may pull therigid force-transmission member (and, thereby, the plunger 144) to movethe security apparatus 100 to the locked position. With such anarrangement, the biasing members 148, 200 may be omitted.

Referring back to FIGS. 1 and 2, the actuator assembly also includes amount 236 extending from the body 168. The mount 236 is configured toreceive a security cable 240 (FIG. 16). The security cable 240 is fixedwithin the mount 236 and secured to an immovable object (e.g., a desk, atable, a wall, etc.) to secure the security apparatus 100, and thereby aconnected portable electronic device, to the immovable object. Theillustrated mount 236 includes a first portion 244 that is fixed to thebody 168 and a second portion 248 that is pivotally coupled to the firstportion 244. The second portion 248 defines a bore 252 that receives thesecurity cable 240.
